For example, fractional distillation is used in oil refineries to separate crude oil into useful substances (or fractions) having different hydrocarbons of different boiling points. The crude oil fractions with higher boiling points:1  have more carbon atoms.or example, fractional distillation is used in oil refineries to separate crude oil into useful substances (or fractions) having different hydrocarbons of different boiling points.

Placenta accreta is a serious pregnancy complication that can occur when the placenta attaches itself too deeply into the uterine wall. Placenta accreta is a serious pregnancy complication that can occur when the placenta attaches itself too deeply into the uterine wall. This causes part or all of the placenta to stay firmly attached to the uterus during childbirth. Placenta accreta can result in severe bleeding after delivery. According to the American Congress of Obstetricians and Gynecologists (ACOG), 1 in 533 American women experience placenta accreta each year. In some cases of placenta accreta, a womanâs placenta will attach so deeply into the uterine wall that it attaches to uterine muscle. This is called placenta increta. It can even go more deeply through the uterine wall and into another organ, such as the bladder.
The placenta is an organ attached to the lining of your womb during pregnancy. It keeps your unborn babyâs blood supply separate from your own blood supply, as well as providing a link between the two.The link enables the placenta to carry out functions that your unborn baby canât perform for itself.lcohol, nicotine and other drugs can also cross the placenta and can cause damage to your unborn baby. Towards the end of your pregnancy, the placenta passes antibodies from you to your baby, giving them immunity for about three months after birth. However, it only passes on antibodies that you already have.
